There is a time and/or date difference between the client and ser

I was able to join Vista to domain (SBS2003) and also I am able to logon with
as admin but I cannot logon with my normal user account. When I try to log on
it only says "There is a time and/or date difference between the client and
server."
I made test user accoun to domain and I was able to logon. It seems that the
time difference occurs only with my normal user account... can anybody help
